if the probability of getting a 6 on a biased dice is 4/5, and you roll it 500 times, how many 6s would you expect to roll

Tresset [83]

I believe the answer would be 400 you take 4/5 and multiply it by 500

The formula for the nth term of an arithmetic sequence can be found using the formula a Subscript n Baseline = a Subscript 1 Bas

Gnoma [55]

The equation of nth term will be written as for n as will be ( $\rm a_n$ - a₁ + d) / d. Then the correct option is D.

The missing options are attached to the picture given below.

<h3>What is a sequence?</h3>

A sequence is a list of elements that have been ordered in a sequential manner, such that members come either before or after.

The formula for the nth term of an arithmetic sequence can be found using the formula given below.

$\rm a_n = a_1 + (n-1)d$
